Decal Dude is a small family business that is committed to making only the best quality vinyl stickers, perfect for indoor and outdoor use. Show everyone that you support America with this sticker. This super high quality sticker set will last for years to come. To install, clean off a flat, smooth surface with a damp cloth. Carefully peel off the sticker backing. Then place the sticker on the surface starting at one edge. Use a hard, flat object, like a credit card, to push down on the sticker and push out any air bubbles.
